Byte already exists for desktop PCs powered by Zorin OS, but it is not an attractive product for me for the following reasons.
Over performance.
Low cost performance.
Since the platform is for mobile devices, it seems to lack maintainability.
I consider desktop platform PCs to be more maintainable and can be used for a longer life time than laptops. For examble, with MIni-ITX, a small enough PC can be built on a desktop platform.
What I miss about my gaming desktop is the ability to just open it anytime and tweek or change out components ..... as I built my last one myself I new her like the back of my hand .... but within 6 months it was obsolete and to be on the cutting edge would need to be up graded ..... that is why I bought something I couldn't get into by just removing a couple of thumb screws .... but I do miss the beastie .....
Anyway my Asus ROG 17in might just as well be a desktop cause it never goes off the table and stays plugged in all the time ....
You could buy a system76 desktop, or purism and install ZorinOS or Dell & HP desktops (look for any of their desktops with Ubuntu support). Or system76/framework for a laptop.
